Answer: 2u+11i-3j
Step-by-step explanation: plug in -11i+3j for v
distribute negative sign
In ΔCAD and ΔCBD,
CD = CD [ Common side ]
AD = BD [ CD is the perpendicular "bisector" of AB ]
∠CDA = ∠CDB [ CD is the "perpendicular" bisector of AB ]
Thus, ΔCAD and ΔCBD are congruent triangles. [ SAS congruency ]
If these triangles are congruent, then AC = BC.
2x = 3x -10
x = 10.
Answer:
x intercept = -7/2
y intercept = 21/5
Step-by-step explanation:
-6x +5y = 21
To find the x intercept, set y=0 and solve for x
-6x +5(0) =21
-6x =21
Divide each side by -6
-6x/-6 = 21/-6
x = -21/6 = -7/2
To find the y intercept, set x=0 and solve for y
-6(0) +5y = 21
5y =21
Divide each side by 5
5y/5 =21/5
y = 21/5
The second choice should be correct
